Pass Box – Dynamic

A dynamic pass box is a cubicle box which has got interlocked doors located on both sides. This protects the controlled environment from being polluted while the transfer of material is taking place inside. Static pass boxes are used to transfer materials between two rooms of equal cleanliness levels and are designed for minimal personnel movement while dynamic pass boxes are used to transfer materials from uncontrolled to controlled environments. Dynamic pass box works like an airlock or laminar air flow unit. A pass box, which is also called a transfer hatch or SAS pass (sterile access system), works as a barrier between areas with different levels of cleanliness when materials do have to be moved. The equipment is used to transfer material from an area of lower cleanliness to an area of higher cleanliness, and vice versa.
